The Wright brothers spent ten months following the fatal crash making engineering improvements to the airplane.

The machine evolved cosmetically over the course of its production with incremental engineering improvements to the suspension and brakes.

Together, all these engineering improvements had a common goal: To continually increase the transmission's performance rating without compromising its installation complexity or proven reliability.

Improving quality and allowing thinner walls was accomplished through many engineering improvements, including reducing the number of cores required to cast an engine block.

Four N1 test launches were attempted in 1969, 1971, and 1972 and all were failures, despite engineering improvements after each crash.

For example, technological requirements can spur engineering improvement, which means employing engineers.

With engineering improvements, the team bested the Gamera I endurance effort by 24 seconds.

Subtle engineering improvements, like their crude tree elevators.

Bowman was engaged engineering improvements on the facilities and defenses of Gulf Coast harbors for nine years.

The 1941 Mercury Eight got all-new styling and some engineering improvements.
